Definitions
- the invention relates to a carrier element made of a contact-laminated Foil material with a cemented and IC chip surrounded by plastic that fits into a recess an identification card with the release of an all-rounder Gap can be installed, the contact-laminated film of the carrier element overlaps the recess on the edge, and a manufacturing device therefor and one with it produced ID card.
- Such a carrier element is from US Pat. No. 5,027,190 known. This consists of an insulating carrier material with laminated metallic contacts on which in a recess of the insulating material of the electronic IC chip is attached. On the insulation material is a heat seal adhesive layer with a recess applied around the IC chip. An epoxy drop bulges the recesses and closes the IC module limited by the heat seal adhesive.
- FR 23 37 381 is made of a carrier element an insulating material plate known on which the IC chip is cemented on and with block contact strips is laminated.
- the IC chip is covered with a synthetic resin encased.
- the height of the support element with the encased IC module is so large that it is inserted in an ID card leaving a gap is covered like a dome by a film that protrudes beyond the standard thickness of an ID card.
- DE 30 29 667 C2 describes such a carrier element known with an IC chip that in a recess an ID card is inserted, whereupon the recess is completely filled.
- EP 0 426 406 A2 is a carrier element known that in a device with a molded body Mold chambers is created (see preamble of claim 4), the dimensions of which are smaller on all sides than the corresponding dimensions of the ID card are, so that each with a bonded IC chip together in the molding chamber with a sealing plastic encapsulated central IC area of the carrier element in the Insert recess of the ID card spaced on all sides is.
- the carrier element preferably consists of Glass fiber epoxy, and it is cast with one of the Edge area with a central area Sealing resin strips in an edge recess of the ID card, which is made of ABS plastic, cemented.
- EP 0 344 058 A1 is an identification card known (see preamble of claim 7), in which a support element on the edge with a circumferential Sealing strip is cemented.
- the support element is a section of a contact-forming metal strip, on which an IC chip is contacted and one Insulating film is applied in the central area.
- the IC chip with the contacts is up to the edge of the sealing strip sufficiently sealed with a drop of plastic, however, the sealing strip for the rest to be connected to it Surface of the card body recess from that Plastic drops are kept free.
- the solution is that the carrier element first with the cemented IC component and the connection bonds down into one with a two component epoxy potting compound completely or almost filled to the brim Molding chamber of a molding device is inserted so that the edge overlap of the support element on the Edge of the molding chamber of the molding device rests, and then the carrier element is covered with a pressure plate and so that it is pressed into the molding device so that the Excess epoxy resin mass from the molding chamber on the side emerges and there is a very thin epoxy layer on the edge the molding chamber on the edge overlap of the carrier element trains, and then the filled molding device heated until the epoxy resin mass has set and then the carrier element is removed from the mold.
- the device for performing the method is in the claim 4 marked.
- the mold chambers in one same grid are arranged in which the carrier elements can be produced on a carrier substrate as a multiple benefit and be equipped with IC components.
- the ID card equipped with the carrier element is in the Claim 7 marked.
- the process has proven itself with different carrier materials, e.g. Glass fiber film, polyimide film, proven, the as elastic, thin foil conductor base materials are commercially available.
- carrier materials e.g. Glass fiber film, polyimide film, proven, the as elastic, thin foil conductor base materials are commercially available.
- a two-component epoxy resin of medium hardness has proven itself because it binds well with the carrier film as a thin layer and an elastic transition and coating to the IC chip forms.
- the pot life of such a two-component epoxy resin mixture is several days under normal conditions. However, the mixture binds in the mold at about one temperature from about 120 ° within 15 minutes.
- the molding device can be made of metal, e.g. B. Manufacture light metal with simple means. A such shape is made with a thin release liner Lined with silicone rubber so that the demoulding of the hardened epoxy resin is easily possible.
- Figure 1 shows an enlarged section through a Molding device (3) comprising a base plate (35) a molded body (30), in which a molding chamber (31) is introduced and on which the carrier element (1) so is applied that the IC module (12) with the Bond connections (11) protrude into the molding chamber.
- the Carrier element (1) is from a pressure plate (36) covered.
- In addition to the mold chamber (31) are around these around excess chambers (32A). These are used in the molding chamber (31) introduced two-component epoxy resin to record, which when immersing the IC chip (12) is excess and out of the molding chamber (31) is pressed out laterally as soon as the shape between the plates (35, 36) are pressurized.
- a thin epoxy resin layer (20) forms between the Carrier element (1) and the top of the molded body (30) that extends to the excess chambers (32A).
- the Shaped body (30) is preferably made of a release agent for Epoxy resin made, namely from silicone rubber suitable strength, so that after curing the Two-component epoxy makes demolding easy can take place.
- the potting compound that the IC module with surrounding the bonds forms a closed one Potting jacket (2), which is flexible in the thin Epoxy layer (20) that runs very well on the Carrier element, which consists of a plastic film, is liable.
- the mold chambers (31) and the excess chambers (32A) with Provide draft angles and along their edges with concave curves (R1, R2). Also the edge transitions to the thin epoxy layer (20) designed with a convex rounding (R3).
- the carrier element (1) is known on the top Way provided with contact surfaces (10), either directly through larger openings in the carrier element or through vias (13) with bond wires (11) Connection contacts connected to the IC module (12) are.
- the mold chambers (31) are filled with epoxy resin, and the shape is equipped with the carrier element and with the Pressure plate (36) is covered, the excess Epoxy resin squeezed into the excess chambers (32A), and then the whole shape becomes about a quarter of an hour long heated to a temperature of 120 ° C, so that Epoxy resin reacts and hardens.
- the carrier element (1) is removed from the mold and trimmed, that the parts that protrude beyond the excess chambers (32A) be removed.
- Figure 2 shows a molding device (3) with a supervision on the molded body (30), in which a plurality of mold chambers (3) in are arranged in a grid which corresponds to a corresponding one Grid arrangement of the contact areas and the IC components on a multiple use of a carrier element film corresponds.
- the mold chambers (31) are each on their Longitudinal and transverse sides with the excess chambers (32A, 32B) surround. This multiple form allows the Casting process including the following curing perform extremely efficiently.
- Figure 3 shows an enlarged cross section through a ID card (4) with a recess (40), which of a support element (1) is covered so that its Contact surfaces (10) point outwards and the IC module (12) with its epoxy potting jacket (2) in the Immersed recess (40).
- a recess 40
- the encapsulation jacket (2) Leave a gap (42) on all sides, so that there is buckling and Shear forces from the ID card not on the Potting jacket (2) and therefore not on the IC module transfer.
- the thin epoxy layer (20) which is on the side of the encapsulation jacket (2) on the carrier element (1) extends, provides an extremely good liability of the Gluing between the support element and the Card inner material.
- the recess (40) is preferably with a lamination film (41) above the encapsulation jacket (2) covered, leaving a slight residual gap to this remains.
